Fix PDF Submit by Email Button Not Working in Chrome Viewer
Question details
The 'Submit by Email' button in a PDF form triggers no action when clicked inside Google Chrome, preventing users from submitting the document.

- Product
- Google Chrome PDF Viewer
- Device & OS
- not provided
- Scenario
- A user is trying to submit a fillable PDF form directly from their web browser using an embedded mailto action button.
- Observed behavior
- The button does nothing when clicked in Chrome, even though the exact same file and button work perfectly in dedicated desktop software like Adobe Reader.
Verify that your computer has a default email application (such as Outlook or Windows Mail) configured properly, as PDF submit buttons rely on system-level email settings to launch.
Download and Open the PDF in a Dedicated Reader
Since Chrome's built-in viewer restricts advanced PDF JavaScript and actions, downloading the file to your computer is the most reliable workaround.
Web browsers prioritize speed and security, often disabling complex PDF features. By using a dedicated desktop application, you can bypass browser limitations and utilize the full functionality of interactive forms.
Click the 'Download' or 'Save' icon located at the top right corner of the Chrome PDF viewer to save the form.
Select a destination folder on your computer, such as your Desktop or Documents folder, and save the PDF file.
Locate the downloaded file, right-click it, and select 'Open with' followed by a dedicated reader like WPS Office or Adobe Acrobat Reader.
Click the 'Submit by Email' button within the dedicated application. Your default email client will now launch with the file attached.

Force Chrome to Download PDFs Automatically
Adjust Chrome's site settings to automatically download PDF files instead of attempting to display them, ensuring forms are always opened in a compatible desktop application.
Use an Alternative Web-Based Submission Method
If the form must be processed directly through a web browser, it is better to convert it into a standard HTML web form.
Use WPS Office for Reliable PDF Form Submission
WPS Office provides robust desktop support for interactive PDF forms, including complex fields and mailto actions. By managing your fillable PDFs in WPS Office, you eliminate browser compatibility issues and ensure all action buttons function perfectly.
- 1. Install WPS Office: Download and install WPS Office free on your computer.
- 2. Open the form: Right-click your interactive PDF form and select 'Open with' > 'WPS Office'.
- 3. Fill out the fields: Complete all the required text fields, checkboxes, and dropdowns directly within the software.
- 4. Submit the document: Click the 'Submit by Email' button to automatically generate the email message via your system's default email client.

Frequently Asked Questions
Why does Chrome not support PDF submit buttons?
Chrome uses a lightweight, secure built-in PDF viewer designed primarily for reading. It intentionally strips out or ignores advanced Adobe JavaScript and specific action triggers, like mailto, to protect users from malicious scripts and improve browsing performance.
How do I fix the mailto link not opening my email client?
Ensure that you have a default email client (like Outlook, Windows Mail, or Apple Mail) assigned in your operating system's default apps settings. If you use browser-based webmail exclusively, you may need to install a browser extension to handle mailto links correctly.
Can I enable Adobe Reader plugins in modern Chrome?
No. Modern versions of Google Chrome no longer support NPAPI plugins. This means you cannot run the native Adobe Acrobat plugin directly inside the browser window, requiring you to download interactive forms for desktop viewing.
Are there other browsers that support PDF submit buttons natively?
Older browsers like Internet Explorer historically supported these features via ActiveX plugins. However, almost all modern browsers (Edge, Firefox, Safari) now use their own secure viewers that limit interactive script actions, making desktop software the best solution.
